We're calibrating using the i8254 timer, and the corresponding timecounter has a pretty narrow mask so wraparound can occur multiple times. I wonder if we should just skip late calibration if the i8= 254 is the only reference clock. Could you please show a verbose dmesg from the broken kernel? --=20 You are receiving this mail because: You are the assignee for the bug.=
